<p>该<code>maxLines</code>参数的工作方式与您对<code>Text</code>小部件的使用方式相同。如果没有<code>maxLines</code>指定参数，则<code>AutoSizeText</code>仅根据可用的宽度和高度来适应文本。</p>

<p>以<code>AutoSizeText</code>开头<code>TextStyle.fontSize</code>。它测量生成的文本并重新调整它以适应其债券。但是，您可以设置结果字体大小的允许范围。</p>
<p>随着<code>minFontSize</code>您可以指定最小的字体大小。如果文本仍然不适合，将按照 处理<code>overflow</code>。默认<code>minFontSize</code>值为<code>12</code>.</p>
<p><code>maxFontSize</code>设置最大可能的字体大小。如果<code>TextStyle</code>继承字体大小并且您想限制它，这很有用。</p>

<p>您可以同步多个<code>AutoSizeText</code>. 他们将符合他们的界限，并且<code>AutoSizeText</code>同一组中的所有人都具有相同的大小。这意味着他们将字体大小调整为具有最小有效字体大小的组成员。</p>

<h2 id="富文本">富文本</h2>
<p>您还可以将富文本(如不同的文本样式或链接)与<code>AutoSizeText</code>. 只需使用<code>AutoSizeText.rich()</code>构造函数(它的工作原理与<code>Text.rich()</code>构造函数完全相同)。</p>
<p>你必须要知道的唯一的事情是字体大小的计算工作原理如下：<code>fontSize</code>在<code>style</code> 参数<code>AutoSizeText</code>(或继承<code>fontSize</code>，如果没有设置)作为参考。</p>
<p>例如：</p>
<div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-dart" data-lang="dart">AutoSizeText.rich(
  TextSpan(text: <span style="color:#e6db74">&#39;A really long String&#39;</span>),
  style: TextStyle(fontSize: <span style="color:#ae81ff">20</span>),
  minFontSize: <span style="color:#ae81ff">5</span>,
)
</code></pre></div><p>文本将至少是其原始大小的 1/4 (5 / 20 = 1/4)。
但这并不意味着所有的<code>TextSpan</code>s 都至少有 font size <code>5</code>。</p>
